Control a browser via Chrome DevTools Protocol (CDP) proxy. Use when: (1) navigating to URLs and reading page content, (2) taking screenshots, (3) executing JavaScript in the browser, (4) clicking elements or filling forms, (5) searching and installing Chrome Web Store extensions, (6) interacting with web APIs that require a real browser. NOT for: simple HTTP requests (use curl), local file operations, or when no CDP proxy is available.
Grafana Cloud Application Observability (APM), Frontend Observability (RUM/Faro), and AI Observability. Covers RED metrics (Rate/Error/Duration), service maps, span metrics from traces, Faro JavaScript/React SDK for browser instrumentation, session replay, AI/LLM model monitoring, and integration with traces/logs/profiles for full-stack correlation. Use when setting up APM, configuring frontend monitoring, analyzing service performance, or monitoring AI/LLM applications.
Fetch real-time web data via the hasdata CLI. Use when the user wants search results, news, fact-checks, product or seller info, current prices, reviews, real-estate listings or sold comps, vacation rentals, local-business contact details, job postings, salary research, search trends, images, flights, social profiles, or to scrape any URL (HTML / markdown / AI-extracted JSON). Also use when the user asks to summarize a web page, ground a prompt with current information, verify a URL is live or render a JavaScript-heavy page, monitor a price over time, find a phone number or address for a business, build a competitor map, identify recent sold comparables, gather employer reviews, fan out a list of items to per-item details, or check what's being said online about a topic right now.

Node.js/TypeScript SDK for the iii engine. Use when building workers, registering functions, or invoking triggers in TypeScript or JavaScript.
OpenTelemetry browser/RUM mechanics for SPAs and MPAs. Use for “browser OTel,” “frontend observability,” “Web Vitals,” `sdk-trace-web`, `WebTracerProvider`, `browser-sdk`, browser instrumentations, page-load or route tracing, sessions, clicks, console capture, JavaScript errors, or frontend-to-backend trace correlation. Browser telemetry is privacy- and volume-sensitive, and experimental packages move quickly. Not for Node.js service instrumentation or Collector-only configuration.
Comprehensive code review skill for TypeScript, JavaScript, Python, Swift, Kotlin, Go. Includes automated code analysis, best practice checking, security scanning, and review checklist generation. Use when reviewing pull requests, providing code feedback, identifying issues, or ensuring code quality standards.
Vue 3 - Progressive JavaScript framework with Composition API, reactivity system, single-file components, Vite integration, TypeScript support
Guidance for bypassing HTML/JavaScript sanitization filters in security testing contexts. This skill should be used when tasked with finding XSS filter bypasses, testing HTML sanitizers, or exploiting parser differentials between server-side filters and browsers. Applies to CTF challenges, authorized penetration testing, and security research involving HTML injection and JavaScript execution through sanitization bypasses.
Complete guide for @solana/kit - the modern, tree-shakeable, zero-dependency JavaScript SDK from Anza. Covers RPC connections, signers, transaction building with pipe, signing, sending, and account fetching with full TypeScript support.
Use this skill when you need to test or evaluate LangGraph/LangChain agents: writing unit or integration tests, generating test scaffolds, mocking LLM/tool behavior, running trajectory evaluation (match or LLM-as-judge), running LangSmith dataset evaluations, and comparing two agent versions with A/B-style offline analysis. Use it for Python and JavaScript/TypeScript workflows, evaluator design, experiment setup, regression gates, and debugging flaky/incorrect evaluation results.
Analyze codebases for anti-patterns, code smells, and quality issues using ast-grep structural pattern matching. Use when reviewing code quality, identifying technical debt, or performing comprehensive code analysis across JavaScript, TypeScript, Python, Vue, React, or other supported languages.
Finds all REFACTOR markers in codebase, validates associated ADRs exist, identifies stale markers (30+ days old), and detects orphaned markers (no ADR reference). Use during status checks, before feature completion, or for refactor health audits. Triggers on "check refactor status", "marker health", "what's the status", or PROACTIVELY before marking features complete. Works with Python (.py), TypeScript (.ts), and JavaScript (.js) files using grep patterns to locate markers and validate against ADR files in docs/adr/ directories.
